WiFi : Direct firmware load for iwlwifi-cc-a0-56.ucode failed

Dear All,
When booting, I’m getting the following error:

iwlwifi 0000:02:00.0: Direct firmware load for iwlwifi-cc-a0-56.ucode failed with error -2

The WiFi works properly, but I’m wondering where this error comes from.
There is no iwlwifi-cc-a0-56.ucode in the /usr/lib/firmware/ directory, only the file iwlwifi-cc-a0-59.ucode.
Could it be a typo somewhere: 9 mistaken for a 6?
Who could answer this question?

Thanks for your help.

Weird, this certainly is available in kernel:

You should open a bug report

I reported the bug here

No, I mean you should report this to CL

I reported the bug on the Clear Linux bug tracking system as well.
Thanks for the advice.

Specifically for CL, those firmwares are installed by a “linux-firmware” package, which is supposed to include all those iwl* wireless firmwares:

I’m not sure why your specific firmware is not installed. But when you’re waiting for the fix, you can try to manually install the missing on from upstream, by just simply copying that file to /usr/lib/firmware


Just extract it and install the missing one

Thanks for your help.
Unfortunately, the file iwlwifi-cc-a0-56.ucode is not contained in the archive you mention.

Sorry I got lost. 56 is missing from upstream. So this IS a upstream bug.

I found a “fix” online… Not sure whether this works

sudo ln -s /lib/firmware/iwlwifi-cc-a0-55.ucode /lib/firmware/iwlwifi-cc-a0-56.ucode
